BIOLOGICAL ACCELERANT AND APPLICATION THEREOF

The disclosure belongs to the technical field of wastewater treatment and in particular relates to a biological accelerant, comprising the following components in parts by mass: 1- 9 parts of vitamin H, 0.5-3.5 parts of 6-benzyl purine, 2-15 parts of aspartic acid, 0-6 parts of glycine, 0-8 parts of glutamic acid, 0-4 parts of flavin adenine dinucleotide, 0-4 parts of humic acid, 0-3 parts of sodium anthraquinone-2-sulfonate and 0-3.5 parts of 1,2- naphthoquinone-4-sulfonic acid, wherein the parts by mass of the six components of glycine, glutamic acid, flavin adenine dinucleotide, humic acid, sodium anthraquinone-2-sulfonate and l,2-naphthoquinone-4-sulfonic acid are not simultaneously 0. Compared with the prior art, the biological accelerant of the disclosure is nontoxic and free of secondary pollution to the environment. Therefore, the biological accelerant of the disclosure can be used for rapid recovery of nitrifying bacteria after inhibition from heavy metals in wastewater treatment
